A top executive at a Missouri mental health company has pleaded guilty to helping bribe Arkansas lawmakers to influence state legislation and boost company profits.

Marilyn Nolan, former CEO of Preferred Family Healthcare Inc., pleaded guilty last week to conspiracy in federal court in Springfield, Missouri, according to court records.

She admitted to stealing millions with other executives at Preferred Family, which she said violated federal laws that prohibit nonprofits from making campaign contributions or lobbying, the Arkansas Democrat-Gazette reported.
